Chick-Fil-A has been tied to an anti-gay group that promotes “coming out of homosexuality” and opposes same-sex marriage.

The Georgia-based restaurant chain is listed as a co-sponsor of Pennsylvania Family Institute’s “The Art of Marriage” events, two workshops scheduled to take place in south-central Pennsylvania Feb. 11-12.

After the gay website GoodAsYou.org posted an ad for the event, subtitled “getting to the heart of God’s design,” Chick-Fil-A denied its corporate sponsorship.

In a statement posted on Facebook, the company wrote, “As our fans, you know we do our best to serve our local communities and one of the ways we do that is by providing food to schools, colleges, civic groups, businesses, places of worship, not-for-profit groups, etc. At his discretion, the local (i.e., Pennsylvania) operator agreed to simply provide a limited amount of food. Our Chick-Fil-A operators and their employees try very hard every day to go the extra mile in serving ALL our customers with honor, dignity and respect.”

However, GoodAsYou.org reports that Chick-Fil-A “is practically joined at the hip with the entire ‘protect marriage’ movement” through its charitable arm, the WinShape Foundation. The foundation supports the National Organization for Marriage’s Ruth Institute, as well as “ex-gay” activists like Alan Chambers.

WinShape also sponsors events for Focus on the Family Institute and the Family Research Council, which are among the most vehemently anti-gay groups in the country. Both were designated hate groups by the Southern Poverty Law Center for spreading lies about LGBT people that reflect tactics used by Nazis to provoke hatred of Jews.
